iMac (2009)  OS X El Capitan v  10.11.6

Sirs, A few days ago I downloaded and installed the latest release of python 3.8.3.

All seemed normal at first until I tried to Cut & Paste parts of a script I was working on in the IDLE
environment. The following are screen shots that are generally self explanatory;
        
As can be seen, the cut and copy are greyed out and inoperative and I don?t remember the "set" and "clear" Breakpoints, at the bottom.  It is as if nothing had been selected.
Such a situation makes the editor practically unusable so I quit out of the IDLE and Python.

To see if it had also effected the normal Finder environment I opened a text editor file and got the following:
      
Indicating the OS was also effected and  I don?t have BBEdit ( top line of bottom panel) installed and it, needs sorting but (top panel) I did follow up on pip and found it to be superseded by vision 20 and have since upgraded 'pip', which I first had trouble getting PY3.8 to recognise. That has been sorted but the problem remained so, in the end I trashed python 3.8 and reinstalled py3.7 and the main fault disappeared. viz;
     
The top panel has change but I don?t understand it. I assume it wants me to look up Pc\Desk??
 
Since then I have tried reinstalling py3.8 twice but the same problems come back. The problem comes and goes with the installation of python3.8.

Does anyone have any idea what the problem might be ?

If it might effect :- I did have a little trouble with the OS native Python 2.7 wanting to own the new pip installation but that was overcome. If it?s of any help this is current Py3.7 terminal list;
      

Best regards
Don B.

I get the same behaviour on macOS 10.15.5, both with 3.8.3 and the 3.9 beta. 3.7.4 works correctly.   This happens both in the interactive shell and in edit windows.  I?d guess this is a problem with the bundled copy of Tk.

Could you file a bug on bugs.python.org <http://bugs.python.org/>?

It looks like this problem was caused by a change a couple of months ago for Issue39885:

https://bugs.python.org/issue39885

which had the side effect of disabling the cut and copy context menu items.

A fix for that regression was just merged yesterday so the problem should be resolved in the next set of releases,
3.8.4 and 3.7.8, which should both be available by mid-July.

I verified the Idle copy/cut context menu problem exists in macOS El Capitan and macOS Catalina 10.15.4.  It occurs in both the Shell and files.

Idle?s menu bar Edit -> Copy and Edit -> Cut options still work just fine.  So Idle is still very usable.

The keyboard shortcuts also still work:
	<command>c == copy
	<command>x == cut

So, there are multiple ways to copy/cut in Idle, even though there appears to be a problem on the context menu.

Are you referring to TextEdit or some other editor?

No, Idle is not causing any problems in TextEdit, or any other editor.  You may not have BBEdit installed at the moment, but you (or someone else) installed it sometime in the past.  You are seeing detritus from that earlier deleted installation.   Idle knows absolutely nothing about BBEdit or any other editor for that matter.

I also upgraded pip (both El Capitan and Catalina), but had no problems with it.

I didn?t reinstall the earlier version of Python, because the only problem with Idle is the context menu.

> The top panel has change but I don?t understand it

I don?t know what you mean by ?top panel?.  Do you mean the macOS menu bar that is displayed when you are using Idle or TextEdit?  

> . I assume it wants me to look up Pc\Desk??

No, it doesn?t ?want? you to look up anything.  When you highlight something in TextEdit and use the context menu with it, one of the options is to look up that selection in a dictionary.  It?s there to make life easier for you ? a lot of folks like looking up word meanings.  It?s totally up to you as to whether you want to do that look up or not.  In this case you selected the text ?System-Pc\Desktop\scene3??, which is why that showed up in the context menu.  If you selected some other text, then it would show up in the context menu instead of your earlier selection.

The only problem I saw was a minor issue with Idle?s copy/cut context menu items.

On macOS the system uses Python 2.7.  Therefore, if you install Python 3.x, there will be two Python versions installed on your system.  To make it easier to use both versions: 
?python?, ?pip?, etc, without a version, runs Python 2.7.
?python3?, ?pip3?, etc, runs Python 3.x.  The exact 3.x.y version depends on your PATH.

The documentation recommends invoking pip as a module on systems with multiple versions installed, such as macOS:
